Izidingo ezintathu ezinkulu zebhethri lesitoreji samandla, ukuphepha kubaluleke kakhulu
Isitoreji samandla se-Electrochemical sithathwa njengendlela eyinhloko yokugcinwa kwamandla ohlelweni lwamandla esizayo, ibhethri nama-PC yinani eliphakeme kakhulu nezithiyo ekhasini eliphakeme, impilo ephansi kanye nezindleko eziphansi. Phakathi kwazo, ukuphepha kuyisihluthulelo. Abanye ochwepheshe bemboni bathi, manje isitshalo samandla esitoreji samandla e-electrochemical sikhula ngokushesha, kepha inkinga yezokuphepha iyi-botleneck yokuthuthuka kwayo okukhulu, isitshalo samandla e-Beijing Energy Storalier kanye ne-Tesla Australia Energy Stored Project of the Energy Storage Indunziso ye-Alal.
Kuze kube manje, imibono ekhombisa ngokusheshisa ukuthuthukiswa kokugcinwa kwamandla okusha ibeka ukusungulwa kwamazinga wobuchwepheshe kanye nokuphathwa komlilo, kuqinisa ukuphathwa kwezokuphepha ngomlilo njengenqubo eyisisekelo; Ngokuphepha okuphezulu, izindleko eziphansi, ukuthembeka okuphezulu, impilo ende nezinye izici zentuthuko ende; Qinisekisa ukuphepha kocwaningo lobuchwepheshe be-Electrochemical Energy Seorth Reserty nokunye. Ikhomishini Yezokuthuthukiswa Kwezwe kanye ne-National Energy, ibhodi le-National Energy ukuhlela ukubelwa kweziteshi eziphephile ze-Electrochemical Ukugcina Iziteshi Zokubonisana (okusalungiswa), ukuqinisa ukuphathwa kokuphepha kwangaphambi kokugcina.
Ukuphepha okuphezulu, impilo ende, ukugqamisa kwebhethri yebhethri ye-nickel-metal hydride
Idatha ye-China Battery Indilinga Association ikhombisa ukuthi ukuphepha okuphezulu kwe-nickel-metal hydride kagesi, impilo yayo ende eyenziwe nge-hydrogen storacties, ngeke iqhume futhi ishise izingozi, ububanzi be-monomer amandla afinyelela ku-140Wh / kg; impilo yokujikeleza impilo efinyelela ku-3,000, ukushaja okungajulile nokukhipha umjikelezo wombuso kuze kube yizikhathi eziyi-10,000 noma ngaphezulu; ingasetshenziswa izikhathi ezingaphezu kwe-10,000; ingasetshenziswa izikhathi ezingaphezu kuka-10,000. Izikhathi ezingaphezu kuka-10,000; kungagcina isilinganiso esiphakeme sokushaja kanye nokukhipha ku-40 ° C ~ 60 ° C. I-ToyotA Hev Car Global SALES ifinyelele ngaphezu kwezigidi eziyi-18, futhi ifakwe kabanzi ngamabhethri e-nickel-metal hydrid, akukaze kube khona icala elilodwa lezingozi zebhethri zokulwa, ukuphepha okuphezulu kwebhethri kuqinisekiswe ngokuphelele.
Ngaphezu kwalokho, ukushaja kwebhethri nokukhishwa kwe-diskarging ukuguqulwa kwamandla wamakhemikhali namandla kagesi, izinga lokushisa linomthelela omuhle ekuphenduleni kwamakhemikhali. Iziteshi zamandla ezitoreji zamandla zingaphandle kakhulu, izinhlobo eziningi zamabhethri zithinteka yimvelo kanye lokushisa, zikhawulela indawo yeziteshi zamandla futhi zinciphise amandla okugcina amandla. Amabhethri we-nickel-metal hydrid emazingeni okushisa aphansi kakhulu kanye nokushisa okuphezulu kwecala elihle kakhulu nokukhipha amandla, ukuze indawo yesiteshi sokugcina amandla iguquguquke ngokwengeziwe, okulula, okungcono, okuye kwaba ukubamba iqhaza kwayo emncintiswaneni wezobuchwepheshe bebhethri "kanye namaphoyinti".
Eqinisweni, amabhethri e-nickel-metal hydrid kuhlelo lokusebenza lwemakethe yokugcina amandla abe yisakhiwo. I-2020, i-nickel-metal hydride ye-battery energy sergy stored coledgey Kuyaqondakala ukuthi uNilar ugxile ekuhlanganiseni kwamandla okuvuselelwa kwamandla nokugcina, amandla okulinda kanye nezinhlelo zokukhokhiswa izimoto zikagesi, ukutshala imali ukugqugquzelwa inkampani kuzohlanganiswa nezinhlelo zemakethe yezentendezeli noma zengqalasizinda. Ngokusho kwama-Frontiers ePolymer Science, iqembu likaStanford University lithuthukise ibhethri le-nickel-metal hydride (NI-MH) lokugcina izinsiza, ngaphandle kwesengo lokugcina umlilo noma i-runaway ephansi, kanye nezindleko eziphansi zokushisa, kanye nezindleko eziphansi. Iqembu likaCui lizokwakha iyunithi lendiza elinomthamo wesitoreji ama-2 megawatts ngo-2021, futhi amacebo wokwandisa amandla alo aze afike ezikhathini ezingama-20 ngemali ngo-2022.
